T 0 all whom it may concern.

Be it known. that I, JAMns SHANNON, a. subject of the King of Great Britain and Ireland, residing at 37 Marquess Road, Canonbury, in the administrative county of London, England, have invented certain new anduseful Improvements in Cooking Stoves, of which the following is a specification.

This invention relates to cooking stoves, and has for its obj eot toenable stoves adapted to burn coal and the like to be easily and readily converted into oil burning stoves.

With this and other ob ects 1n view the lnventlon comprises the various novel features of construction, combination and ar- I converted cooking .a line 2-2 ofFigl,

rangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended. v t

.In the accompanying drawings in which similar parts are denoted by like characters of reference Fig. 1 is a view in. front elevation of k stove fitted with av single oil vapour burner. v v

Fig. 2 is a view in transverse section on Figs. 8 and 4 are views in plan of an adjustable heat, retaining plate or slab for the bottom of the grate, the former showing its adaptation to grates of asinall size and the latter to grates ofala'rger' size.

-5. is a View 'n side elevation of one of the elementsof said plateor slab.

Figs. 6 and T are views in end an'd side elevation respectively of one of the fillingin or gap pieces for use with the adjustable plate or slab, v i v Figs, 8 and '9 are views in elevation an plan respectively of a detachable or hollow cone or bellrshape'd grid for the heat re taining plate or slab.

be located in that part of therange'under I the grate usually occ upi'ed by the ash pan.

Cooperating with the burner is the usual fuel ta'nk2 whichis provided withhieans for creating pressure therein and is con-.

nected to the vapourizer by the pipe 3. on

a metallic frame 4' adapted to fit injth'e grate in the place occupied by the fire bars is placed a. heat retaining plate or slab of fire brick or "othersuitable material which has a suitably slia 1){ed' perforation 6, and on the upper side of said plate orslab j above said perforation is formed or mounted Q .70 saidgrid are placed a number of thejo'rdis nary heat retaining-balls or blocjks-9r The perforation 6 in heat retaining plate or slab is so shaped and located as to. substantially a. cone-shaped gridj8. Around jan'dj above coincide with the "shape and position "of the head ofthe burneir. u

In order to facilitate "the [fitting of; the; Y heat retaining plate orlslab 5 in rang'es'haw ing grates of "different sizes said platefor slab may be Ii llClG lIl two orl more pieces,

the preferred construction to [make it in four sections of similar 'shap'e a-nd size which when ljaicl to,' g"etl 1'erwill'form' a slab which will fillthe bottom of agi ate of minimum size shown in Fig. 3 and which. can be sp'read to form plate "or slab which-willfit a grate of a larger-size."

by the use of four filling-in or'gap'piec'es 7 adapted to occupy the spacesjbetween thfe four sections of the plate or slab asjshofwniII Fig Y. v i.

In order to support the filling-inp in relation to the seotions'of the pleat-rslab they are made of a T shape cross section the vertical parts being adapted WVhen. more than one oil 7 burner orl'a with a plurality of perforations 6 as shown as shown inFigs. 3, 4,10 and 11 saidgrid is made as a separate element as shown in Figs. 8, 9 and 12.

The front of the space below the grate of the stove is closed bya suitably shaped, plate e in- Figs. 10 and, 11 and when the plate or slab 5 is made in one piece, the grid 8jispreferably made integral with same but when said plate'or slab is made insections i to fit in the spaces" between the. adjacent sections of the, plate or slab and the h'o ri I zontal parts to rest in the tops ofs'aidt j'secj 'tions'v burner with a pluralityof bni iier heads is employedtheplate or "slab 5'is provided 10 for the purpose of enclosing the burner and protecting same from draughts. This plate can be conveniently suspended from the lower bar of'the front of the grate and is provided with a slot 10 to permit of the passage of the fuel and induction pipes 3 and 1", and with one or more adjustable orifices 11 to permit of the adjustmentof the amount of air passing to the burner head.

- cated above the opening in the heat retaining plate, and a plurality of heat retaining balls located around and over said grid.

2. The combination with a cooking stove having a grate adapted to burn coal, of an oil vapour burner adapted to be placed in.

the space in the stove under the grate usually occupied by the dust pan, a perforated heat retaining plate adapted to fit in the bottom of thegrate, a hollow cone-shaped grid located above the opening in the heat retaining plate, and a plurality of heat retaining balls located around and over said grid, and a plate adapted to close the space below the plate in which the vapour-burner is located said plate being provided with a slot for the passage of the fuel and induction pipes.

3. The combination with a cooking stove having a grate adapted to burn coal, of an oil vapour burner of a size adapted to be placed in the space inthe stove under the grate usually occupied by the dust pan, a perforated heat retaining plate adapted to fit in the bottom of the grate, ahollow coneshaped grid located above the opening in v the heat retaining plate, a plurality of heat retaining balls located around and over said grid, and a plate adapted to close the space below the grate in which the vapour burner is located said plate beingprovided with a slot for the passage of the fuel and induction pipes and with adjustable auxiliary air inlets.

, 4, In combination with a cooking stove having a grate adapted to burn coal, an oil vapour burner adapted to be placed in the space in the stove under the grate usually occupied by the dust pan, a sectional perforated heat retaining plate adapted to fitin the bottom of the grate, a bell-shaped grid adapted to fit over the opening in the heat retaining plate, means for varying the size of said plate, and a plurality of heat retaining blocks located around and over said grid.

5. In combination with a cooking stove having a grate adapted to burn coal, an oil vapour burner adapted to be placed in the space in the stove under the grate usually occupied by the dust pan, a sectional perforat-ed heat retaining plate adapted to fit in the bottom of the grate, a hollowconeshaped grid adaptedto it over the opening I on the heat retaining plate, means for varying the size of said plate, a plurality of heat retaining balls located around and over said coact with said sectional heat retaining plate, a plurality of heat retaining blocks lo- .cated around and over said grid, and aplate adapted to close the space below the grate in which the oil burner is located.

7 For the conversion of a stove adapted to be heated by a coal fire into a stove adapt ed to be heated by an oil burner, a plate of fire-brick or like heat retaining material for replacing the fire bars forming the bottom of the grate, said plate having a central perforation and a hollowcone-shaped grid located abovesaid perforation.

8. For the conversion of a stove adapted to be heated by a coal fire into one adapted to be heated by an oil burner, an adjustable perforated plate of fire-brick or like heat re taining material adapted to take'the place of the fire-bars forming the bottom of the grate, said plate comprising four sectionsof equal size and shape and four filling-in pieces to fit between said sections, and a hollow coneshaped grid adapted to be placed on the top of said perforated plate above the opening therein.
